Your diagnose sounds reasonable to me. I don't use roxygen2 myself, so I can't really help here (and this is one of several reasons: it adds another layer of potential problems to the documentation process). Perhaps someone who uses roxygen2 can comment? Or perhaps they (roxygen2 developers) have a GitHub or email list?
